Test Grass Terrain Skill

Verifies that the grass terrain implementation is working correctly in both the editor and game.

What This Tests

The grass terrain feature includes:

• Material 1 defined as grass (green colors, grass glyphs)
• Default terrain: 12×12 grass center + 2-patch water border
• Terrain height: Above water level (0xA000 vs water at 0x8000)
• Camera position: At correct height to see terrain

Quick Test - Editor

Launch editor and verify:

Copy./.run/asciiid

Expected output in console:

CopyTerrain initialized: 144 grass patches, 112 water patches

Expected visual:

• Center area: GREEN grass with quote marks " apostrophes ' and backticks `
• Border (outer 2 patches): BLUE-GRAY water with commas , spaces and exclamations !
• Clear boundary between grass and water

Quick Test - Game

Launch game and verify:

Copy./.run/game

Expected:

• Same grass center + water border layout
• Terrain visible (not underwater)
• Player spawns on grass terrain

Detailed Testing Steps

See TESTING_GUIDE.md for comprehensive testing:

1. Visual Verification - Check grass/water appearance
2. Camera Controls - Test VIEW PITCH and YAW sliders
3. Material Painting - Paint with Material 0 (water) and 1 (grass)
4. New Map Test - Create new map, verify default terrain
5. Console Output - Verify initialization message
6. Save/Load Test - Save map, reload, verify persistence

Common Issues

All water (no grass visible):

• Terrain height might be 0 instead of 0xA000
• Check asciiid.cpp:8263 and game_app.cpp:1862

No tiles visible:

• Camera height might be mismatched
• Check asciiid.cpp:8329 (pos_z should be 0xA000)

Random colors instead of grass:

• Material 1 might not be initialized
• Check asciiid.cpp:483-516 for grass definition

Implementation Files

Key files for grass terrain:

• asciiid.cpp:483-516 - Material 1 grass definition
• asciiid.cpp:8263 - Terrain height (0xA000)
• asciiid.cpp:8266-8322 - Material initialization
• asciiid.cpp:8329 - Camera height (0xA000)
• game_app.cpp:1862 - Game terrain height
• game_app.cpp:1864-1884 - Game material init

Instructions

When the user asks to test grass terrain:

1. Check if editor/game is already running
2. Launch appropriate executable
3. Verify console output shows "Terrain initialized: 144 grass patches, 112 water patches"
4. Ask user to confirm visual appearance matches expected layout
5. If issues found, check the common issues section above
